FIG. 3 illustrates a side view of the automated guided vehicle according to an embodiment of the disclosure, and FIG. 4 illustrates a schematic view of the automated guided vehicle of FIG. 2 . In FIGS. 3 and 4 , for the convenience of description, part of the vehicle body 21 is transparent to show the internal structure of the automated guided vehicle 20. As shown in FIGS. 3 and 4 , the automated guided vehicle 20 according to an embodiment of the disclosure comprises a conveyor belt 31, a sliding rail 32, a tag installation device 33, a tag reader 34, and a control unit 36.

The control unit 36 may comprise one or more processing units, such as an application processor (AP), a modulation or demodulation processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a video encoder or decoder, a digital signal processor (DSP), a baseband processor, or a neural-network processing unit (NPU), etc. Different processing units may be independent components, or integrated in one or more processors. The control unit 36 can generate operation control signals according to the instruction operation code and timing signals, and complete the control of fetching and executing instructions. In some other embodiments, a storage device may be provided in the control unit 36 to store instructions and data. For example, the storage device in the control unit 36 may be a cache memory. The storage device can store instructions or data that the control unit 36 has just used or recycled. If the control unit 36 needs to use the instruction or data again, the instructions or data can be accessed from the storage device.

The conveyor belt 31 is installed on the car body 21 and has a sensor 35 (third detection device). In an embodiment, the sensor 35 can be a weight sensor to detect whether there is a component 30 on the conveyor belt 31. When the sensor 35 detects that the weight of an object on the conveyor belt 31 exceeds a predetermined value (for example, 100 grams), it means that the component 30 has been placed on the conveyor belt 31 from the feed inlet 23, and the sensor 35 (third detection device) outputs a fourth control signal to the control unit 36. The control unit 36 triggers the conveyor belt 31 to convey the component 30 according to the fourth control signal, and conveys the component 30 to the first predetermined area A along the moving direction 39.

In FIG. 4 , the sensor 37 (first detection device) is positioned in the first predetermined area A to detect the position of the component 30. When the component 30 is delivered to the first predetermined area A by the conveyor belt 31, the sensor 37 outputs the first control signal to the control unit 36. The control unit 36 drives the tag installation device 33 according to the first control signal. According to an embodiment of the disclosure, the sensor 37 may be a proximity sensor, an infrared sensor or a light blocking sensor.

Referring FIG. 3 , the triggered tag installation device 33 attaches the tag 40 to the component 30. FIG. 3 shows the component 30 without the tag 40, before the component 30 has passed through the tag installation device 33. After being processed by the tag installation device 33, the component 30 on the slide rail 32 has been attached with the tag 40. According to an embodiment of the disclosure, the tag 40 has a communication chip, a sensor, and an activation switch. When the tag installation device 33 installs the tag 40 on the component 30, the tag installation device 33 simultaneously presses the activation switch to activate the tag 40. Thus, the tag 40 is in a readable and writable state. Next, the control unit 36 writes the component information and information of a predetermined period to the activated tag 40 through a tag writing tool (not shown in the figure), and then the tag 40 is driven by the conveyor belt 31 to the second predetermined area B. At the same time, the smart tag 40 starts counting time elapsing. The second predetermined area B is located at the slide rail 32, and the slide rail 32 is provided with a sensor (the second detection device, not shown) in the second predetermined area B to detect the position of the component 30. When the component 30 is detected in the second predetermined area B, the sensor (second detection device) outputs a third control signal to the control unit 36. According to an embodiment, the sensor (the second detecting device) located in the second predetermined area B may be a proximity sensor, an infrared sensor, or a light blocking sensor.

The sliding rail 32 has a latch located in the second predetermined area B, and the preset state of the latch is retracted under the sliding surface of the sliding rail 32. When the control unit 36 receives the third control signal, the control unit 36 triggers the latch according to the third control signal to block the component 30 from moving on the slide rail 32. In an embodiment of the disclosure, the latch is a tenon, and the tenon is protruding from the sliding surface of the sliding rail 32 to block the component 30, so that the component 30 cannot slide down. It is noted that the use of the tenon in this embodiment is only an example, and those skilled in the art can use other methods to make the material 30 stay in the second predetermined area B of the slide rail 32.

When the component 30 stays in the second predetermined area B of the slide rail 32, the tag reader 34 reads the component information, the elapsed time, and the information of the predetermined period of the tag 40. Since the tag 40 continues to accumulate and count time elapsing, when the elapsed time matches the predetermined period, the tag reader 34 outputs a second control signal to the control unit 36. When the control unit 36 receives the second control signal, the latch is triggered by the control unit 36 according to the second control signal to retract below the sliding surface of the sliding rail 32, so that the component 30 is released and is able to move from the second predetermined area B to the third predetermined area C. The third predetermined area C is a component temporary storage area, and from there the component 30 can be taken out from the automated guided vehicle 20 through the component outlet 38. According to the embodiment of the disclosure, the component 30 can be taken out from the automated guided vehicle 20 through the component outlet 38 by manual or industrial robot.

According to the embodiment of the disclosure, the tag 40 may also have environmental detection sensors, including temperature sensors, humidity sensors, air pressure sensors, odor sensors, or ambient light sensors, to detect environmental information around the tag 40. The environment information on the assembly line can be collected through the environment detection sensors of the automated guided vehicle 20 and the tag 40. When the information as to the environment shows an abnormal state, which exceeds a threshold, these sensors may provide the abnormal information to the control unit 36, and the control unit 36 may notify a content management system or cloud server through the antenna 25 for data management. It is noted that the detailed structures and internal circuits of the tag installation device 33, the tag writing tool, the tag reader 34, and the tag 40 described in the embodiment of the disclosure are wholly conventional and will be fully appreciated by those of ordinary skill in the art.

The automated guided vehicle according to an embodiment of the disclosure can transport components between production units. In addition, the automated guided vehicle can control the time of occupation and use time of components at different stages by tags, a tag installation device, and a tag reader. Moreover, replacing the manual installation of tags with a tag installation system can improve the automation of the assembly line. In addition, the component transferring system according to the embodiment of the disclosure is equipped with environment detection sensors on the automated guided vehicle and tags, which can instantly and accurately monitor whether the environment is abnormal and/or requires action, ensuring product yield and improving assembly line safety.
